Pour un calcul précis de taille d'échantillon, précise si ta métrique est binaire (taux) ou continue (moyenne). Pour une métrique binaire, le delta doit être absolu (ex: +2 points de pourcentage) plutôt que relatif, car la variance dépend du taux de base. Si continue, fournis l’écart-type historique. Sans ces infos, les estimations générées seront approximatives.
